I config 640*480 resolution VGA input to get RGB888 TTL output , regisiter list as blow,in black pattern ,R/G/B channel 0 is a hsync waveform.
could you give me a answer ,Tks!

Hi,
Could you please crosscheck your configuration with reference script under ##GR VGA 640x480## at 4682.ADV7441A_Evaluation_Board_Documents.zip
Also refer PLL recommended settings for GR Modes in ADV7441A…
I have already check the setting"##GR VGA 640x480## at 4682.ADV7441A_Evaluation_Board_Documents.zip",There is none similar input format and output format, like VGA input 640*480P60Hz/1280*720P60Hz…
Also refer PLL recommended settings for GR Modes in ADV7441A hardware manuals.
Note: Normally HS timing is based on a pixel clock count, VS, DE and FIELD are based on the HS counts. FIELD and DE existence are based on the format, FIELD delineates the odd and even fields of a frame in interlaced formats and DE defines the active video in progressive formats.
Thanks,
Poornima

Please let me know, Have you verified with RGB444 TTL output ? or you have issue only with RGB888 TTL output.
